The invention discloses a steel rail corrugation detection method and device, a storage medium and a computer program. The method comprises the steps that detection result data corresponding to at least two detection features used for representing steel rail corrugation are obtained; wherein each detection feature corresponds to one piece of detection result data; determining a corrugation area where corrugation occurs based on the detection result data, and calculating the confidence degree of each corrugation level in the corrugation area; the confidence coefficient is used for representing the probability of corrugation grade occurrence; performing data fusion on the confidence coefficients of the same corrugation level determined by the at least two detection features of the same corrugation area to obtain the fusion confidence coefficient of the same corrugation level; and detecting the occurrence of corrugation in the steel rail section based on the fusion confidence of each corrugation level of each corrugation area. According to the invention, data fusion is carried out on the level confidence of different detection features, corrugation is detected based on the fusion confidence, and the accuracy of corrugation detection is improved.
